Speaking at observances marking the 80th anniversary of the outbreak of World War II in Warsaw, President RP said that, "we remember and will remember, being grateful to all those who were fighting and those who sacrificed their lives for a free world."

We cannot allow armed aggression to continue, because it is our responsibility to our societies and to the societies of Europe and the world. May the drama of World War II, which was experienced by the whole world, never be repeated, President said.

"This was the Second World War, which ravaged the world, which will never be forgotten since we must never forget it. We must never forget it even when all the eyewitnesses are gone," President Andrzej Duda said.
